Release 1.15.0

1. Release Prep

  • Verify that the previous release branch commit hash matches the last release tag. Investigate with previous RE if they do not match
  • Create release branch with name. Ex: release-1.15.x
  • Build draft release notes, see release_notes_template.md
  • Release specific code changes. Make the following changes in a single commit so it can be cherry picked into master later.

    • Bump self-reference version in base/gitrepository.yaml

    • Update chart release version chart/Chart.yaml

    • Bump badge at the top of README.md

    • Update /Packages.md with any new Packages

    • Update CHANGELOG.md with links to MRs and any upgrade notices/known issues. release-diff update link for release

    • Update README.md using helm-docs. Overwrite the existing readme file.

      # from root dir of your release branch
docker run -v "$(pwd):/helm-docs" -u $(id -u) jnorwood/helm-docs:v1.5.0 -s file -t .gitlab-ci/README.md.gotmpl --dry-run > README.md

2. Test and Validate Release Candidate

Deploy release branch on Dogfood cluster

  • Connect to Cluster
  • Update bigbang/base/kustomization.yaml & bigbang/prod/kustomization.yaml with release branch.
  • Verify cluster has updated to the new release

    • Packages have fetched the new revision and match the new release

    • Packages have reconciled

      # check release
watch kubectl get gitrepositories,kustomizations,hr,po -A
# if flux has not updated after 10 minutes.
flux reconcile hr -n bigbang bigbang --with-source
# if it is still not updating, delete the flux source controller 
kubectl get all -n flux-system 
kubectl delete pod/source-controller-xxxxxxxx-xxxxx -n flux-system

Upgrade Notices

Resources

Bigbang has begun to implement resource requests and limits on pods in preparation of setting OPA constraints to deny. If you notice multiple pod restarts check for OOMKill termination errors, and pod limits may need to be increased.

MINIO INSTANCE CRITICAL UPGRADE INFORMATION - PLEASE READ BEFORE UPGRADING

If you have enabled the Minio Cluster Instance in the 'minio' namespace, this upgrade requires a backup and restore of your Minio instance buckets. Failure to do so will result in data loss during the upgrade.

By default, the update of the Minio Instance helm chart to V4.1.2 will keep the 2.0.9 instances in place and operational. This allow a backup to be performed on the operational Minio Instances. After the backup is complete, an upgrade to the V4.1.2 instance is required. This is accomplished by setting the upgrade key/value [in the values file] (show below) to TRUE.

# When true, upgradeTenants enables use of the V4.* Minio Operator CRD for creation of tenants is enabled.
addons:
  minio:
    values:
      upgradeTenants:
        enabled: false

After execution of the helm chart with this value set to true, the new V4 instances will be running and you can restore the backup data to the new instances.

NOTE: If you have not enabled the deployment of a Minio Instance before the V4.1.2 release, you must set the above mentioned upgradeTenants/enabled value to TRUE or the helm deployment will fail

One of the easiest ways to backup your Minio instance is to use the Minio MC command line tool on a different system. The MC command line tool can be found here: https://github.com/minio/mc or you can use the Iron Bank approved container located at registry1.dso.mil/ironbank/opensource/minio/mc:RELEASE.2021-06-08T01-29-37Z.

mc alias set <alias name> HOSTNAME ACCESSKEY SECRETKEY
mc mirror <alias name>/ <local storage location>

Istio upgrade from 1.8 to 1.9

This release upgrades istio to 1.9.7. Because of this all pods with an istio-proxy sidecar must be restarted to pull in the newest sidecar version.

Mattermost default value change

To allow for defining replica count and resource requests/limits, users is set to null by default. Changing this will negate replica and resource values and Mattermost may not run due to OPA Gatekeeper constraints.

To set a replica count greater than 1 requires an enterprise license, and can be configured like the following example:

addons:
  mattermost:
    values:
      enterprise:
        enabled: true
      replicaCount: 3

Setting a user value is not supported due to OPA constraint issues

If you want to use Mattermost's user/size value you will need to handle OPA violations and exceptions yourself since this is not BB supported. If all of these considerations have been accounted for and you still want to deploy with Mattermost's user sizing it can be done by setting the value as in this example:

addons:
  mattermost:
    values:
      users: 1000
